The present invention relates to clamps for use upon hair curlers of a type embodying a mandrel upon which the hair is adapted to be wound, and has for its primary object to pro- .vide a clamping device of this character for clamping a heat composition pad in a position for partly surrounding the hair after the same has been wound on the mandrel.

One of the important objects of the present invention is to provide a hair clamping device of this character embodying a plurality of pivotally connected clamping jaws having their free edges adapted to close upon the hair inwardly of the mandrel and embodying a heat insulation face adapted for resting upon the scalp of the person 7 to prevent contact therewith by the metal part of the clamp.

A further important object is to provide a clamping device of this character which is open at its outer portion to facilitate the insertion and removal of the chemical heating pad into and out of position within the clamp.

An additional important object is to provide a chemical heating pad embodying a double compartment within each of which the powder may be positioned and arranged whereby the powder in the respective compartments may produce successive heating action while maintained in a position within the clamp and wtihout necessitating removal of the heating pad from the clamp.

An additional object is to provide a clamp for hair curlers embodying a scalp spacing element carried by the clamp to eliminate the use of a separate spacing device generally employed for preventing direct contact of the clamp with the scalp and thus enable the placing of the clamp and curler more closely to the scalp to produce a closer curl.

Another object is to provide an apparatus of -'this character of simple and practical construction, which is neat and attractive in appearance,

efficient and reliable in performance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantagesreside in the de tails of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming "part hereof, wherein like numerals refer to like parts throughout and in which-.-

Figure l is a side elevational view with parts broken away and shown in section.

Figure 2 is a top plan view. Figure 3 is an end elevational view. Figured is a transverse sectional view taken substantially on a line "4+4 of Figure 1.

Figure 5 is a perspective view of the detachable insulating pad adapted to separate one of the clamping jaws from contact with the skin of a person. 7

Figure 6 is an end elevational view showing the device in position ready for use.

Figure 7 is a perspective view of one of the chemical heating pads, and

Figure 8 is a transverse sectional view therethrough.

Figure 9 is a perspective view of one of the jaws 56.

Fig. 10 is a perspective view of the lining l8, and

Figure 11 is a sectional view of the lining l8.

Referring now to the drawings in detail, the numerals 5 and 6 designate a pair of relatively elongated clamping jaws of arcuate shape in cross section, one longitudinal edge of the jaws being adapted to close against each other in clamping position as shown at l and the inner or pivoted longitudinal edges of the jaws being spaced apart as shown at 8 to provide an elongated opening between the jaws for a purpose to be hereinafter explained.

Adjacent each end of the jaws are provided arms 9, the free ends of the arms of the respective jaws being pivotally connected as at I0 to permit the opening and closing movement of the jaws in a manner as will be apparent. Each of the arms 9 are provided with notches 9 for receiving the ends of an arcuate leaf spring I I to yieldably urge the jaws in a closed position. Each of the longitudinal edges of the jaws, at their inner ends are provided with manipulating handles l2. Stops l3 adjacent the ends of each of the arms 9 cooperate with each other to limit the opening movement of the jaws.

The longitudinal free edges of the jaws, as'

well as the longitudinal inner edges of the jaws are provided with notches l4 adapted to receive partitions l5 formed within channel l6 of the edge portions ll of rubber insulation strips l8 which form a lining for the inner arcuate surface of the jaws, the respective longitudinal edges of the jaws being seated in said channels to maintain the lining in position. The edge of the lining l8 at the free longitudinal edges of the jaws are provided with longitudinally extending beads l9 which constitute a base adapted to contact the scalp 20 of the person upon which the device is placed as will be apparent from an inspection of Figure 4 of the drawings, to space the clamp outwardly from the scalp, this beading being of any desired cross sectional form, either polygonal as shown in Figure 4 or rounded as shown in Figure 3.

Each end of the jaw is provided with an opening 2i as shown in Figure 3 within which hooks 22 projecting outwardly from the end edges of a rubber insulation pad 23 may engage, to detachably secure the pad against the outer surface of one of the jaws to prevent contact of the metal surface of the jaws with the scalp or skin of a person when the device is placed about a curl adjacent the back or the neck and wherein the weight of the clamp and curler would have a tendency to cause the same to sag downwardly. One of the longitudinal edges of the pad 23 abuts the edge of the base l9 as will be apparent from an inspection of Figure 3 of the drawings, and it will also be apparent that the detachable pad 23 may be placed on either side of the clamp.

The clamp is designed for use primarily upon a hair curling device shown at 24 which embodies a mandrel 25 about which the hair 26 is adapted to be wound and held in position by clamps 2'! and 2?. After the hair has been wound upon the mandrel the clamp forming the present invention is placed thereon and through the opening at the top of the clamp is positioned a chemical heating pad 28 shown in detail in Figures 7 and 8 of the drawings.

The pad 28 is in the form of a substantially rectangular flat envelope preferably formed of suitable paper and within which a chemical powder 29 is positioned, of a character well known in the art to generat steam upon the application of moisture thereto. The outer surfaces of the pad 28 are perforated as shown at 31 to provide for the escape of steam therefrom and a partition 36 is provided in the pad to form the same into chambers 32 and 33 within each of which the powder 29 is contained. The partition 3!] is parallel to the respective flat surfaces of the pad and accordingly when one side of the pad is subjected to moisture to generate steam the opposite side of the pad is not affected thereby. Accordingly, in the hair curling operation with the pad placed in position as shown in Figures 4 and 6 of the drawings, the surface of the pad immediately adjacent the hair is moistened whereby to produce "steam, the partition 31 preventing the escape of "applied to the outer surface of the pad and an the steam upwardly or through the pad and causing the same to be directed against the hair.

Should the first application of heat be insufficient to produce the desired curl, moisture is then outer separate cover 34 is then placed over the .outer surface of the pad whereby the steam gen erated from the powder in the second compartment will be forced through'the partition 3! against the hair and prevented from escape outderstood from the foregoing without further detailed explanation.

Having thus described the invention, what I claim is l. A clamp for hair curlers comprising a pair of elongated, transversely arcuate clamping jaws connected at their inner longitudinal edges in spaced parallel relation to provide an opening between the jaws for access within the jaws, spring means yieldably closing the jaws, manipulating I handles for the jaws and insulation means carried by the free edges of the jaws to prevent contact of the jaws with the scalp of a person. 7
